摘      要：This paper proposes a robust controller to improve power system stability and mitigate subsynchronous interaction(SSI)between doubly-fed induction generator(DFIG)-based wind farms and series compensated transmission lines.A robust stability analysis is first carried out to show the impact of uncertainties on the SSI *** uncertainties are mainly due to the changes in the power system impedance(e.g.,transmission line outages)and the variations of wind farm operating ***,using theμ-synthesis technique,a robust SSI damping controller is designed and augmented to the DFIG control system to effectively damp the SSI *** output signals of the supplementary controller are dynamically limited to avoid saturating the converters and to provide DFIG with the desired fault-ride-through(FRT)operation during power system *** proposed controller is designed for a realistic test system with multiple series capacitor compensated *** frequency of the unstable SSI mode varies over a wide range due to the changes in power system topologies and wind farm operating *** performance of the proposed controller is verified through electromagnetic transient(EMT)simulations using a detailed wind farm *** results also confirm the grid compliant operation of the DFIG.
